LIQUID-DISPENSIN G APPARATUS.

To all whom it mag concern:

Be it known that we, CHARLES R. MoDoN- ALD and ALBERT E. BEVAN, citizensof the United States, residents of xlTPOIl, county of Summit, and Stateof Ohio, have invented new and useful Improvements in Liquid- DispensingApparatus, of which the following is a specification, the principle ofthe invention being herein explained, and the best mode in which we havecontemplated applying that principle so as to distinguish it from otherinventions.

Our invention relates to liquid-dispensing apparatus and particularly toapparatus of this character designed for the dispensing of soft drinks,cream for coffee, etc., in restaurants, soft drink parlors, etc.,carrying on a retail trade; also, for the dispensing of syrups at sodafountains. The objects of the invention are to provide apparatus of thischaracter which may be economically built, easily and accuratelyoperated, which shall dispense at each operation substantially the sameamount of liquid, in which the liquid may be kept cool and refreshing,and which shall be satisfactorily sanitary.

The annexed drawings and the following description set forth in detailcertain means embodying our invention, such means constituting, however,but one of the various forms in which the principle of the invention maybe applied.

In said annexed drawings:

Figure 2 represents a fragmentary vertical section, taken in the planeindicated by the line 11-11, Figure 1; v

Referring to the annexed drawings in which the same ordinals indicatethe same respective elements in the several views, I indicates a maincasing by the ordinal 1, having a cover 2 formed with doors 3 throughwhich ice may be dumped to retain cool the liquid contents of areceptacle 4 which is mounted upon posts 4 in the casing 1 and formedwith a filling opening covered by a door 5, all as plainly indicated inF igure 1. This liquid receptacle 4 is formed with a well 6, the same inthe form of apparatus illustrated, being aseparate cylindricalreceptacle mounted by means of the flange 6 upon the floor of the mainreceptac184 and being in vertical alignment with a a lateral,vertically-extending channel portion 4 formed in the receptacle 4, asplainly shown in Figures 1 and 4:. However, we do not lay any stressuponthe particular connection of the well 6with the receptacle 4 or theformation of the channel 4 or even whether or not the receptacle 4 andwell 6 are integral or separate members. The receptacle 4 is supportedso as certainly to drain into the well 6 so that it is evident, if thereis any liquid in the receptacle 4, the well 6 will receive the same andit is the design of the apparatus to dip this liquid accurately andcleanly in measured amounts from this well 6 and dump the same into anydesired receptacle exteriorly of the casing 1. This dipping is donethrough the medium of a bucket 7 adapted to be raised and loweredthrough the medium of a vertically reciprocable rod 8 having a fingerpiece 9. The discharge of the measured liquid is effected through thecasing opening 10 normally covered, except at discharge periods,

Ill)

by means of a door 11 pivoted at one edge upon a horizontal axis 11.This casing opening 10 is in reality formed in an upwardly projectingcover member 12 formed with a vertical extension 13 serving as a bearingsurface for the reciprocation of the rod 8, all as plainly shown inFigure 1. This member 13 also serves as a support to which is attachedthe hinge 14 of the door 11. The bucket7 is secured to the lower end ofthe rod 8 by means of a yoke 15 having arms 15 in the lower end of whichtrunnions 16, provided upon or formed integrally with the bucket 7 arepivoted. The bucket 7 is so weighted and pivotally hung as normally tomaintain the position shown in Figure 1. It is evident that thisposition will enable the bucketwhen pulled upwardly by the rod 9 to dipan accurate measured amount of the liquid in the well 6. Secured to theouter wall of the bucket 7: is a lug 17 having an inclined groove 18,this groove 18 being bounded upon both sides by walls 18, one of whichis partially cut away at its upper side so that a pin 19 projectinginwardly from the casing member 12, as plainly shown in Figures 1 and 5,will pass through the opening 18 and intersect the other wall 18, whenthe bucket 7 is raised, as shown in Figure 5, thus causing the bucket 7to swing upon the trunnions 16, thus discharging the contents of thesame through the opening 10, the mouth 20 of the bucket 7 being of aformation as plainly shown to effect such discharge in a verysatisfactory manner. Before this discharge actually takes place andsubstantially concurrently with the tipping of the bucket 7, the door 11has been opened in the following manner: Pivoted in the oppositelydisposed walls of the casing member 12 by means of its arms 22 is ayokeshaped wire frame 21, plainly shown in Figure 1, in the positionwhich the same occupies, when the bucket 7 is in its lower position. Asthe bucket 7 is raised by the rod 8 the yoke 15 intersects the arms 22of the frame 21 and swings the latter outwardly upon its pivoted ends tothe position shown in Figure 5, this movement of the frame 21 causingthe same to pass through the opening 10 which will result in said frame21 raising the door ll to the position shown in Figure 5, as will bereadily understood. When the fingerv piece 9 is released or when thebucket 7 is positively lowered by means of pressing down said fingerpiece 9, the weight of the door 11 will force the frame 21 back into theposition shown in Figure 1, thus both closing the discharge opening 10and putting the frame 21 into position for again opening the door 11when the bucket 7 is again next raised.

In order more accurately to disclose how the lug 17 and the pin 19realign the bucket upon its downward movement to quickly tilt the sameinto its normal position, reference is made to Figures 8 to 12,inclusive. It will be noted that the bucket drops or is pushed from thedumping position shown in Figure 5 to the position shown in Figure 8 andthat then the pin 19 intercepts the upper wall 18 and, acting thereonand traveling in the groove 18, swings the bucket, as the latter islowered, first into the position shown in Figure 10 and then into theposition shown in Figure 11. It is not meant that the realigning ofthebucket is effected in a jerky manner but simply that Figures 10 and 11 1illustrate two positions of the bucket as it is being continuouslytilted from the position shown in Figure 8 to the position shown inFigure 11.

The discharge from the bucket 7 is so complete, and the tilting of thesame again into its normal position so quickly effected, i. e., from theposition shown in Figure 5, to its normal upright position, that thereis practically no drip of the liquid from the mouth ing in retailquantities of any liquid and we claim it for such general purposes, butwe have particularly designed the same for the keeping and dispensing ofcream for coffee, as also soft drinks, and syrups for sodas, inretail'quantities.

What we claim is: z

1. In liquid-dispensing apparatus, the combination of a liquidreceptacle formed with a downwardly-extended well compartment; a bucket;means for raising and lowering the latter from and into said well, thereceptacle being formed with a discharge opening; a pivotally-mountedcover for said opening; a pivoted frame controlled by the bucketmovements for opening said cover, the latter being free to close underthe force of gravity and adapted when closing to move said frame back tonormal position; a lug attached to said bucket and formed with aninclined groove; and a pin fixed in the wall of said receptacle adjacentsaid cover in the line of movement of said lug and adapted to engage thewalls of said groove to tilt the bucket upon its upward movement and torealign the bucket upon its downward movement.
